Here's another Lego brick builder for OpenSCAD. Use it stand-alone to make bricks in odd sizes. Or import it into your own project to make your thing connect with real Lego. The 5x3 brick in the stl-file is just an example. Supports any standard Lego length, width and height. Also makes smooth bricks without the knobs/studs. This is my first OpenSCAD project. It was made just for fun and experimenting. Please add some useful comments.To use this in your own projects add: use <path_to_this_file/lego_brick_builder.scad> brick (length, width, height [,smooth]); Length and width are in standard lego brick dimensions. Height is in flat brick heights, so for a normal lego brick height = 3. Add optional smooth = true for a brick without studs. Use height = 0 to just put studs/knobs on top of other things.
